Can anyone tell me the right way to enter the elastoplasic properties of a material in Creo/WF 5.0? I have the true stress/strain curve entered. With the "Use best fit coefficients checkmarked the curves look good. However the Tensile Yield stress is at 0. If I try to hit ok it doesn't let me. It says I must have a value greater than 0. If I uncheck the box and put in the correct value the curve shifts way up. Any thoughts?
